Description

[Technical field]

[0001] The present invention relates to a packaging container obtained by molding a synthetic resin sheet, and to a structure in which the food placement surface is inclined so that the food can be presented in an attractive manner and the food can be prevented from shifting out of position. [Background technology]

[0002] In supermarkets and convenience stores, prepared foods are sold in sheet-formed containers with transparent lids, and appearance is important to increase consumer purchasing power. However, it is difficult to arrange food in a three-dimensional manner in a tray-like container with a flat bottom. In particular, sashimi is thin and lacks volume, so it is often arranged on a base of tsuma (a garnish) such as daikon radish. However, this not only increases the cost of the garnish, but also goes against the international initiative of the Sustainable Development Goals (SDGs) to reduce food waste if the garnish is not eaten and the amount of food wasted increases.

[0003] In response to this, there have been sheet-formed containers with an inclined food serving surface (for example, Patent Documents 1 and 2). These sheet-formed containers with an inclined food serving surface make it possible to present food in a three-dimensional, voluminous and attractive way. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2015-224040 A [Patent Document 2] JP 2016-182988 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, when the serving surface is inclined, food is likely to slip and become misaligned, and this cannot be corrected when the lid is closed, so such an unattractive product discourages consumers from purchasing it.

[0006] In this regard, Patent Document 1 discloses a tray container for serving food in which the inclined surface 5 on which food is served is formed with horizontal convex stripes 12 in the left-right direction and vertical convex stripes 12 in the up-down direction, and it is said that these vertical and horizontal convex stripes 12 can effectively prevent food from shifting out of position. However, since most shifts in position on the inclined surface 5 are due to food sliding down, providing vertical convex stripes 12 on such inclined surface 5, regardless of whether horizontal convex stripes 12 are provided, cannot prevent food from sliding down in that area.

[0007] Meanwhile, Patent Document 2 discloses a food packaging container in which food placement surface 13a is inclined and a second protrusion 14 is provided below it, so that food placed against food placement surface 13a is prevented from sliding off by second protrusion 14. However, because food placement surface 13a is composed of a smooth surface that does not have vertical and horizontal convex stripes 12 as in Patent Document 1, if the container is tilted even slightly when the product is displayed or when a consumer picks it up to evaluate it, the food will slide sideways and become misaligned from side to side.

[0008] In addition, because the food is placed upright, it is difficult for drips and oils from the food to flow down, and the liquid reattaches to the food, impairing its taste and texture. This is more noticeable if the food placement surface 13a has a gentle slope, but if it has a steep slope, the food is more likely to shift from side to side, and the container will have a false bottom rather than a sense of volume.

[0009] To provide a packaging container that can present food in an attractive manner with a suitable volume and can more reliably prevent the food from shifting out of position. [Means for solving the problem]

[0010] In order to achieve the above-mentioned object, the present invention provides a packaging container having a container body formed from a synthetic resin sheet with peripheral walls rising from the bottom and an opening at the top, wherein the bottom has a food mounting section that slopes upward from the front side of the container body to the back side, and the food mounting section has an anti-slip section consisting of a rib with a convex cross-section formed on a sloped surface further forward than the top, and the anti-slip section is composed of a combination of horizontal ribs arranged perpendicular to the slope of the sloped surface and diagonal ribs arranged diagonally to the slope of the sloped surface.

[0011] According to the above-mentioned means, the food placement portion is inclined upward from the front side to the back side of the container body, so that by placing food on this portion, the food can be presented in a three-dimensional, voluminous and attractive manner.

[0012] The inclined surface of the food placement section is formed with a non-slip section made of a rib with a convex cross section, which prevents the food from shifting out of position. That is, among the ribs that make up the non-slip section, the horizontal rib restricts the food from moving up and down the inclined surface by a horizontal component perpendicular to the inclination direction of the inclined surface. In particular, it prevents the food from sliding down the inclined surface. On the other hand, the diagonal rib can be broken down into a horizontal component and a vertical component along the inclination direction of the inclined surface, and while the horizontal component restricts the food from moving up and down like the horizontal rib, the vertical component also restricts the food from moving left and right. Such a non-slip section allows the present invention to maintain the appearance of the food served.

[0013] In addition, the smaller the inclination of the diagonal rib, the larger the horizontal component, and the larger the inclination, the larger the vertical component. However, since the present invention also has horizontal ribs, it is reasonable to make the diagonal ribs inclined at 45 degrees or more in order to ensure the vertical component that cannot be obtained with the horizontal ribs. However, the inclination of the diagonal ribs is not limited to this. Furthermore, the tip shape of the horizontal ribs and the diagonal ribs has a triangular cross section to increase the anti-slip effect, but for soft foods, it may have an arc cross section because it leaves a bite mark. Furthermore, the more horizontal ribs and diagonal ribs there are, the higher the anti-slip effect, but the number is not limited.

[0014] The anti-slip portion can also be formed by intersecting the horizontal ribs and the diagonal ribs, but by forming the horizontal ribs and the diagonal ribs at a fixed distance from each other, the drips and oils that seep out from the food can be discharged from the gaps between the horizontal ribs and the diagonal ribs along the slope to the bottom of the food placement portion, thus preventing the re-adhesion of the exudates to the food and preventing the loss of taste and texture.

[0015] Furthermore, the diagonal rib in the present invention includes two diagonal ribs running diagonally in the same direction connected by an intermediate rib to form a lightning bolt shape. With this type of lightning bolt rib, a total of three straight ribs can provide anti-slip effects according to their respective angles.

[0016] It is preferable that the height of the diagonal rib based on the slope is higher than that of the horizontal ribs. This is because the anti-slip effect of the diagonal rib in all directions can be improved. This height relationship may be at least partial. In other words, it includes cases where a part of the diagonal rib is higher than a part of the horizontal rib, and further, "a part" is a concept that includes not only a part of the rib, but also one of the ribs if there are multiple ribs. In other words, even if a part of the horizontal rib is higher than a part of the diagonal rib, as long as the diagonal rib is higher than the horizontal rib in other parts, the anti-slip effect of the diagonal rib is enhanced in those parts.

[0017] On the other hand, the food placement section preferably has a pair of side guards on the left and right of the non-slip section, along the inclination direction of the food placement section, that are convex in cross section and higher than the height of the horizontal rib based on the slope section. This is because the side guards can prevent food from protruding to the left and right of the food placement section or falling off. Here, the side guards can be connected to the horizontal ribs or the diagonal ribs, but by providing the side guards at a certain distance from the non-slip section, the exudate from the food can flow down the food placement section along the slope section through the gap between the side guards and the non-slip section, preventing the exudate from reattaching to the food. Note that the side guards may be separated not only from the entire non-slip section, but also from either the horizontal ribs or the diagonal ribs, and if there are multiple ribs, they may be only a part of them. Furthermore, one of the pair of left and right side guards may be separated. In addition, the height relationship here also includes a form in which at least a part of the side guard is higher than the horizontal rib, as with the diagonal rib described above.

[0018] Furthermore, the food placement section preferably has an underguard with a convex cross section that is parallel to the horizontal rib below the non-slip section and higher than the height of the horizontal rib based on the slope. This is because the underguard can prevent food from slipping off the food placement section. The underguard can be connected to the diagonal rib, but by providing the underguard at a fixed distance from the diagonal rib, exudate from the food can be introduced into the gap between the underguard and the diagonal rib, reducing or preventing the reattachment of the exudate to the food. Note that the horizontal rib is in a vertically parallel relationship with the underguard and is initially spaced at a fixed distance, so it goes without saying that the exudate can be introduced into the gap. In addition, the height relationship here also includes a form in which at least a part of the underguard is higher than the horizontal rib, as with the diagonal rib and side guard described above.

[0019] The inclination angle of the food placement section is not limited, but as long as the height based on the inclined portion of the underguard is equal to or greater than the height of the side guards, food can be prevented from slipping off even if the inclination angle of the food placement section is relatively large. The height relationship here also includes a configuration in which part of the underguard is equal to or greater than the height of the side guards, which is the same as the height relationship of the diagonal ribs, side guards, and underguard relative to the horizontal ribs described above.

[0020] In addition, it is preferable that the under-guard has a notch portion halfway along its length that connects to the sloping portion, and this notch portion allows food exudate that has flowed down the sloping portion to be drained to the outside of the food placing section, more reliably preventing the exudate from re-adhering to the food.

[0021] Furthermore, by making the side guards and under guards independent of each other and having corner cutouts that connect to the sloped portions at the lower left and right corners of the food placement section, food exudates can be drained to the outside of the food placement section through the corner cutouts as well.

[0022] Furthermore, although the height of the food placing section is not limited, by positioning its top below the opening of the container body, it is possible to achieve a moderate sense of volume for the food served on it while avoiding a too-false feeling.

[0023] The food placement section is not limited to a one-way slope, but may have a mountain-shaped cross section with slopes formed from both the front and back sides of the container body toward the top, in which case food can be placed on two slopes. In this case, the mountain-shaped cross section is a concept that includes specific shapes such as a gable-shaped cross section, an arch-shaped cross section, and a circular arc-shaped cross section.

[0024] Furthermore, the number of food placing sections is not limited to one, but multiple food placing sections can be arranged side by side along the front-to-back direction from the front to the back of the container body and / or along the left-to-right direction of the container body, in which case different types of food can be placed on each food placing section. Effect of the Invention

[0025] The packaging container of the present invention allows food to be presented in an attractive manner with a moderate sense of volume, while reliably preventing the food from shifting out of position, thereby maintaining the attractive appearance of the presented food.

[0027] Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. Fig. 1 shows a packaging container according to a first embodiment, where 1 is a container body and 2 is a lid. In this embodiment, an example is shown in which the lid 2 is closed by external fitting onto the container body 1, but the present invention can employ a conventionally known lid-closing structure. Therefore, a detailed description of the lid-closing structure will be omitted, and the container body 1 according to the characteristic configuration of the present invention will be described in detail.

[0028] The container body 1 has a peripheral wall 4 rising from a bottom 3, forming an opening at the top. The peripheral wall 4 is folded downward via an outward flange portion 5 to form a skirt portion 6. The above-mentioned lid body 2 is adapted to be fitted onto the outside of this skirt portion 6. In this embodiment, the container body 1 has a rectangular shape in a plan view as shown in Fig. 2, but the outer shape in a plan view may be any other polygonal shape, or may be a circle or an ellipse.

[0029] What is important in the present invention is that the bottom 3 is raised in an inclined manner to provide the food placement section 7, and the surface of the food placement section 7 is made non-slip. Specifically, as shown in Fig. 3, the food placement section 7 has an inclined surface 8 that slopes upward ((rising)) from the front side F to the back side B of the container body 1, and below the top 9, a non-slip section 12 is formed on the inclined surface 8 on the front side of the container body 1 by combining a horizontal rib 10 and an oblique rib 11. The horizontal ribs 10 are arranged in a direction perpendicular to the inclination direction of the inclined surface 8, and the oblique ribs 11 are arranged in a direction oblique to the inclination direction of the inclined surface 8. In this embodiment, two oblique ribs 11 with the same oblique angle are arranged above and below the inclined surface 8 in the center of the food placement section 7 to form a diagonal rib group, and a horizontal rib group consisting of eleven horizontal ribs 10 is provided on the left and right of the diagonal rib group to form the non-slip section 12.

[0030] Therefore, food can be arranged in a three-dimensional, voluminous and attractive manner according to the inclination angle of food placement section 7. The arranged food is restricted by anti-slip section 12 from moving up, down, left and right on sloped section 8, so that the original appearance is maintained. That is, the horizontal ribs (horizontal ribs 10) constituting anti-slip section 12 restrict vertical movement, particularly downward sliding due to gravity, while the diagonal ribs (diagonal ribs 11) restrict left and right movement (sideways sliding) in addition to vertical movement.

[0031] Furthermore, the horizontal ribs and diagonal ribs are arranged at regular intervals by making the horizontal ribs 10 and diagonal ribs 11 independent of each other and not intersecting with each other. Therefore, when drips or oil seeps out from the plated food, the drips flow downward to the sloped portion 8 through the gaps between the horizontal ribs (horizontal ribs 10) and the diagonal ribs (diagonal ribs 11), preventing the re-adhesion of such seepage.

[0032] Furthermore, in this embodiment, side guards 13 and underguards 14 are provided on the left, right and bottom edges of food placing section 7. Side guards 13 are vertical rib-like extending up and down sloped section 8 in the direction of the incline of food placing section 7, and underguard 14 is a type of horizontal rib-like extending parallel to horizontal rib 10. These guards 13 and 14 allow food to be presented inside them in an attractive manner and prevent the presented food from spilling out to the left or right from food placing section 7 or slipping down, thereby reliably maintaining the original appearance.

[0033] Furthermore, under-guard 14 is cut away to provide cutouts 15, and side guard 13 and under-guard 14 are separated by corner cutouts 16 at the lower left and right corners of food placing section 7, so that exudate flowing down slope 8 is discharged to the outside of food placing section 7 through cutouts 15 and corner cutouts 16, more reliably preventing re-adhesion. Also, by forming side guard 13 and under-guard 14 at intervals from non-slip section 12 as in this embodiment, the gap can be used as a flow path or storage section for exudate, and the exudate can be isolated from food.

[0034] The horizontal ribs 10, diagonal ribs 11, side guards 13, and underguards 14 all have a convex cross-section, but by setting their respective heights H1 to H4 based on the sloped portion 8 as shown in the following formula, it is possible to achieve both an attractive presentation and an anti-slip effect. H1 <H2<H3≦H4 (where H1 is the height of the horizontal rib 10, H2 is the height of the diagonal rib, H3 is the height of the side guard, and H4 is the height of the underguard 14) In this embodiment, the horizontal ribs 10, diagonal ribs 11, side guards 13, and underguards 14 have a straight apex shape with heights H1 to H4 that are uniform in the length direction, but if the apex is inclined or curved in the length direction or wavy, so that the height is non-uniform in the length direction, the highest parts of them can be set as H1 to H4 according to the above formula. Also, if the above formula is satisfied for at least one of the multiple ribs, the above-mentioned compatible effect can be obtained.

[0035] 3, the height of the food placement section 7 is such that its top 9 is equal to or lower than the height of the opening of the container body 1 (synonymous with the upper surface of the flange section 5). This reduces the feeling of a false bottom, and allows food to be served with an appropriate sense of volume.

[0036] 4 shows the second embodiment, in which the shape of the diagonal rib and the arrangement of the side guard and underguard are changed from those of the first embodiment. That is, the diagonal rib 20 in this second embodiment is formed in a lightning bolt shape by connecting the lower and upper ends of two diagonal ribs 21 and 22 that run diagonally in the same direction with a horizontal intermediate rib 23. This lightning bolt-shaped diagonal rib 20 can also obtain the same anti-slip effect as the diagonal rib group of the first embodiment consisting of the two diagonal ribs 11, as well as the anti-slip effect provided by the intermediate rib 23.

[0037] Additionally, the side guards 24 and under guards 25 are U-shaped and connected at the bottom left and right corners of the food placement section 7, and do not have the corner cutouts 16 or notches 15 of the first embodiment. Therefore, this is suitable for serving food that produces little drips or oil while more reliably preventing it from shifting out of position.

[0038] Furthermore, in the second embodiment, the tip shapes of the diagonal ribs 20 and the horizontal ribs 26 are changed from the triangular cross-section in the first embodiment to an arcuate cross-section, so that the diagonal ribs 20 and the horizontal ribs 26 soften the contact with food and are less likely to leave bite marks.

[0039] 5 shows a third embodiment, in which, in accordance with the container body being long horizontally, the number of diagonal rib groups is 2 and the number of horizontal rib groups is 3. In this way, the number of diagonal rib (groups) and horizontal rib (groups) can be appropriately changed depending on the size and shape of the container body, the type of food, etc.

[0040] As a further modification, in the above embodiment, the food placement section is sloped in one direction, but it is also possible to provide a non-slip slope on the back side for piling food on, giving the whole a mountain-shaped cross section, as shown in Fig. 6. Also, as shown in Figs. 7 to 9, it is also possible to provide multiple food placement sections side by side on the front, back, left and right sides of the container body. [Explanation of symbols]
